Apple today quietly upgraded the performance of its MacBooks and added new performance options for its MacBook Pro models. The 13-inch MacBook systems are now based on the Intel Santa Rosa platform used by the recent MacBook Pro and run on a faster 800MHz system bus in addition to using faster GMA X3100 integrated graphics, which add improved hardware 3D acceleration compared to the GMA 950 used in previous models.

The new configurations are as follows:

Apple has also added a build-to-order option of a 250GB, 5400RPM hard disk. All new configurations are listed as shipping within 24 hours and are available today from the online Apple Store.
